180. The root mean square (RMS) value of a sine-wave current may also be referred to as what value?
The RMS value of a sine-wave current is also known as the effective value because it produces the same heating effect in a resistor as an equivalent DC current. This distinguishes it from the instantaneous value, which is a value at a specific moment, the maximum value, which is the peak amplitude, and the average value, which is zero for a full sine wave cycle.
